GRAIN-CAR DOOR.

SPECIFICATION formingpart of Letters Patent No. 683,718, dated October 1, 1901.

Application filed Tune 14, 1901.

To all whom it may concern:

Be it known that I, GUST YOUNG, a citizen of the United States, and a resident of the city of Hallock, in the county of Kittson and State of Minnesota, have invented certain new and useful Improvements in Grain-Car Doors, of

- which the following is a specification.

The object of'this invention is to produce a grain-car door which will accommodate itself to the movement and jar of the car While in transit and which will at the same time maintain an effectual and continuous contact at all points with the door-posts and door-sill, thus preventing the loss of grain by percolation.

A further object is to provide a suitable means for retaining the doors in an elevated position overhead inside the car when they are not in use. I

These objects are accomplished by the various parts described in the following specification and shown in the drawings, in which similar letters indicate corresponding parts.

Figure 1 is an elevation of the outside of the door. Fig. 2 is an elevation of the inside of the car-door. Fig. 3 is a transverse View of the car-door, showing the door-frame partly in section. Fig. 4 is a top view, partly in section, through line a: m, Fig. 1. Fig. 5 is a top view of a bar at the base of the door, showing laps at the ends. Figs. 6, 7, and 8 are details of mechanism for holding the lower end of the door suspended. Figs. 9 and 10 are details of guides, and Figs. 11 and 12 are details of spurs which are housed by said guides.

In the drawings, A is the door-frame, and B is the door.

0 represents the rafters, to which the door is suspended when ,not in use by means of ears M and swinging hooks N.

D represents guides in which spurs E are housed, said spurs having free movement up and down. The construction of the guides D is fully shown in Figs. 9 and 10. Spurs E serve the double purpose of holding the door vertical when in position for use and suspending the upper end of said door by lugs e, resting upon pins at when the door is not in use. It will be seen by reference to Figs. 11 and 12 that the spurs are formed with channels 6. Said channels engage with ribs d of guides D, as shown in Fig. 4.

F represents keepers which are provided Serial No- 64,5l1. (N0 model.)

with lugsf, through which bolts secure them rigidlyto the door.

f represent-s lugs which extend over and retain in place the bars G and G. Bars G are in three sections at each side of the door, while the corresponding bar G at the base of the door is integral throughout its entire length. Bar G is provided at its ends with laps g, which .overlap the ends of bars G. The side bars G are made in three sections, which are flexibly connected by plates I, as shown. The said bars G and G in cross-section have reversed right angles, as shown in Fig. 4, theexposed angle having attached thereto the lever-rods j. To the inverted angle of the said bars G and G are attached permanently strips H, composed of rubber or other resilient material. Said strips are wider than the said inverted angle and when in action bear against the door-posts and door-sill.

J represents levers which are pivoted to rods j, said rods passing through slots j in the keepers F. r

9 represents very strong springs securely fastened to the keepers F beneath the lugs f, with theirfree ends resting in the exposed angles of. bars G and G, as shown.

K represents 5 wivel tension-bolts divided at their centers and connected by swivel-joints 1c, the said bolts being attached to the doorposts by staples 7c". The free ends of said bolts K are provided with hooks,which en gag with holes at it in the keepers F. 1

L is a sill Weatherstrip, against which the rubber strip H at the base of the door rests.

M represents cars which are bolted to the rafters O. Said ears have curved slots, which receive the spindles n ofthe swinging hook N.

In operation when the door is not used it is raised up until the lugs e of spurs E are above the pins at, when the door is swung within the car, the lugs e resting on the pins 01. The door is then raised to a horizontal position, when the hooks N engage its edges, thus holding it overhead. If one door only is to be elevated, the spindles n of hooks N are allowed to rest in the upper circular openings of the slots m; but if both doors are to be raised their lower ends lap, and to provide more room between the rafters and the points of the hooks the spindle 'n is lowerad to the base of the slot m. When the doors are adjusted for receiving grain into the cars, they are lowered into position and the side levers J arethrown into vertical plane and the lower lever J to a horizontal plane. The springs g, acting on the bars G and G,press the rubber strips 11 against the door-posts and door-sill. The hooks of the swivel-bolts are then engaged with the holes at in the keepers F and then drawn taut by turning the swivelnut. By this means the face of the door is drawn forcibly against the door-posts and the door-sill. By this result, in connection with thecompression of the rubber strips, perfectly-impenetrable joints are secured. The bars G at the sides being in three sections with the rubber strips flexibly accommodate themselves to any twisting or strain to which the cars may be subjected. To disengage the door, the action is reversed, the swivel-bolt is unscrewed, the swivel-hooks removed, and the side levers J forced into ahorizontal position and the lower lever J into a vertical position. By this action the eccentric ends of the levers come in contact with the faces of the keepers F and,.

acting through lever-rods j upon bars G and G, draw said bars and rubber strips away from the door posts and sill, thus releasing the entire apparatus from frictional contact with the door-posts and door-sill.

Having described my invention, I claim as new-- 1. A grain-car door having flexible and resilient jambs attached to its outer face, adjacent to its sides and lower edge and means for holding said jambs .in contact with the door-posts and the door-sill, for the purpose described and set forth.

2. A grain-car door having rubber strips attached to sectional side bars and to an integral base-bar, the said bars and rubber strips running the entire length of the sides and width of the base of the'door, said bars and strips being held in movable position by keepers as shown and described.

3. A grain-car door-having rubber strips attached to sectional side bars, said sectional side bars being pivotally connected by plates and retained in movable position by keepers, as shown and described.

4. A grain-car door having rubber strips attached to sectional side bars and to an integral base-bar, said bars being held in movable position by keepers and operated by levers, being connected thereto by lever-rods which pass through the face-plates of the keepers, the eccentric ends of the said levers bearin g against the face-plates of the keepers when the apparatus is in disengagement with the door posts and sill,as shown and described.

5. A grain-car door having a series of flexibly-jointed bars carrying resilient strips, said bars being held in movable position by keepers which are permanently bolted to the door, aseries of levers connected to the sections of the flexible bars for the purpose of throwing the rubber strips in and out of contact with the door-frame, and swivel-bolts attached to the door-posts, the free ends of said swivelbolts having hooks to engage with suitable orifices in the keepers, as shown and for the purpose described.

6. In combination with a grain-car, a door having spurs attached to its upper corners, said spurs being provided with channels to engage with guides on the door-posts and having lugs to rest on pins in the door-posts, guides which house the said spurs, and L- shaped swinging hooks for holding the doors in an elevated position, said hooks being adjustably connected to ears having verticallydisposed scroll-shaped slots, said ears being attached to the rafters within the car, all as fully described and shown in the drawings.

Signedat Hallock, in the eounty'of Kittson and State of Minnesota, this 4th day of June, 1901.
